This section provides information on sticky load balancers, session expiration, additional Geode property changes, serialization and more.

## <a id="tc_additional_info__section_78F53B3F4301466EA0E5DF277CF33A71" class="no-quick-link"></a>Sticky Load Balancers

Typically, session replication will be used in conjunction with a load balancer enabled for sticky sessions. This involves, among other things, establishing a JVM route (`JVMRoute=value`). Refer to [SpringSource ERS](http://static.springsource.com/projects/ers/4.0/getting-started/htmlsingle/getting-started.html) as a possible [load balancing](http://static.springsource.com/projects/ers/4.0/getting-started/htmlsingle/getting-started.html#load-balancing) solution.

## <a id="tc_additional_info__section_C7C4365EA2D84636AE1586F187007EC4" class="no-quick-link"></a>Session Expiration

To set the session expiration value, you must change the `session-timeout` value specified in your application server's `WEB-INF/web.xml` file. This value will override the Geode inactive interval specified by `maxInactiveInterval` within `context.xml`.

## <a id="tc_additional_info__section_5CE5FF6F55DB462E8B2A336A0AF7515E" class="no-quick-link"></a>Making Additional Geode Property Changes

If you want to change additional Geode property values, refer to instructions on manually changing property values as specified in the Geode module documentation for Tomcat ([Changing the Default Geode Configuration in the Tomcat Module](tomcat_changing_gf_default_cfg.html#tomcat_changing_gf_default_cfg)) and Application Servers ([Changing the Default Geode Configuration in the AppServers Module](weblogic_changing_gf_default_cfg.html#weblogic_changing_gf_default_cfg)).

## <a id="tc_additional_info__section_0013BDC875A44344B7B062F46AFA073C" class="no-quick-link"></a>Module Version Information

To acquire Geode module version information, look in the web server's log file for a message similar to:

``` pre

```

## Object Serialization

Objects managed by the HTTP Session Management Module must be serializable since the session's objects are serialized before being stored in the region.
